CA 2670874

A hole saw having a central body portion adapted to receive a hole saw blade portion. The body and the blade have correspondingly shaped apertures and lugs that co-operate together to hold the blade in place. A locking means further assists in ensuring that the blade remains locked to the body and includes a sliding klatch that engages an aperture in the blade and the body and is itself locked in place to thereby lock the blade to the body.

La présente invention concerne une scie-cloche qui possède une partie de corps centrale conçue pour recevoir une partie de lame de scie-cloche. Le corps et la lame possèdent de façon correspondante des ouvertures de forme particulière et des oreilles qui coopèrent les unes avec les autres pour maintenir la lame en place. Un moyen de verrouillage aide en outre à garantir que la lame reste verrouillée sur le corps et comprend un verrou coulissant qui entre en prise avec l'ouverture dans la lame et le corps et est lui-même verrouillé en place pour ainsi verrouiller la lame sur le corps.
